221 Chelan PUD Hatchery Program Annual Report HCP HC Page ii June 1, 2008 2007 Annual Report PREFACE This annual report is the result of coordinated field efforts conducted by Washington Department of Fish and Wildlife (WDFW), the Confederated Tribes and Bands of the Yakama Nation (Yakama Nation), Chelan County Public Utility District (Chelan PUD), and BioAnalysts, Inc. An extensive amount of work was conducted in 2006 and 2007 to collect the data needed to monitor the effects of the Chelan County PUD Hatchery Programs. This work was directed and coordinated by the Habitat Conservation Plan (HCP) Hatchery Committee, consisting of the following members: David Carie, U.S. Fish and Wildlife Service (USFWS); Jerry Marco, Confederated Tribes of the Colville Reservation (Colville Tribes); Kristine Petersen, National Marine Fisheries Service (NMFS); Shaun Seaman, Chelan County PUD; Tom Scribner, the Yakama Nation; and Kirk Truscott, WDFW. The approach to monitoring the hatchery programs was guided by the “Conceptual Approach to Monitoring and Evaluating the Chelan County Public Utility District Programs” written by Andrew Murdoch and Chuck Peven. Technical aspects of the monitoring and evaluation program were developed by the Hatchery Evaluation Technical Team (HETT), which consists of the following scientists: Matt Cooper, USFWS; Steve Hays, Chelan PUD;

Upper Columbia River Basins Critical Habitat Unit The Upper Columbia River Basins CHU includes the entire drainages of three CHSUs in central and north-central Washington on the east slopes of the Cascade Range and east of the Columbia River between Wenatchee, Washington, and the Okanogan River drainage: (1) Wenatchee River CHSU in Chelan County; (2) Entiat River CHSU in Chelan County; and (3) Methow River CHSU in Okanogan County. The Upper Columbia River Basins CHU also includes the Lake Chelan and Okanogan basins which historically provided spawning and rearing and FMO habitat and currently the Chelan Basin is essential and provides for FMO habitat to support migratory bull trout in this CHU. No critical habitat is proposed in the Okanogan River at this time. Bull trout have been recently observed in the Okanogan River near Osoyoos Lake, but it is unclear if it is essential habitat and what role this drainage may play in recovery. A total of 1,074.9 km (667.9 mi) of streams and 1,033.2 ha (2,553.1 ac) of lake surface area in this CHU are proposed as critical habitat to provide for spawning and rearing, FMO habitat to support three core areas essential for conservation and recovery.

  • GEOLOGIC MAP of the CHELAN 30-MINUTE by 60-MINUTE QUADRANGLE, WASHINGTON by R
    DEPARTMENT OF THE INTERIOR TO ACCOMPANY MAP I-1661 U.S. GEOLOGICAL SURVEY GEOLOGIC MAP OF THE CHELAN 30-MINUTE BY 60-MINUTE QUADRANGLE, WASHINGTON By R. W. Tabor, V. A. Frizzell, Jr., J. T. Whetten, R. B. Waitt, D. A. Swanson, G. R. Byerly, D. B. Booth, M. J. Hetherington, and R. E. Zartman INTRODUCTION Bedrock of the Chelan 1:100,000 quadrangle displays a long and varied geologic history (fig. 1). Pioneer geologic work in the quadrangle began with Bailey Willis (1887, 1903) and I. C. Russell (1893, 1900). A. C. Waters (1930, 1932, 1938) made the first definitive geologic studies in the area (fig. 2). He mapped and described the metamorphic rocks and the lavas of the Columbia River Basalt Group in the vicinity of Chelan as well as the arkoses within the Chiwaukum graben (fig. 1). B. M. Page (1939a, b) detailed much of the structure and petrology of the metamorphic and igneous rocks in the Chiwaukum Mountains, further described the arkoses, and, for the first time, defined the alpine glacial stages in the area. C. L. Willis (1950, 1953) was the first to recognize the Chiwaukum graben, one of the more significant structural features of the region. The pre-Tertiary schists and gneisses are continuous with rocks to the north included in the Skagit Metamorphic Suite of Misch (1966, p. 102-103). Peter Misch and his students established a framework of North Cascade metamorphic geology which underlies much of our construct, especially in the western part of the quadrangle. Our work began in 1975 and was essentially completed in 1980.

    Wild and Scenic Rivers Eligibility Assessment Wenatchee National Forest APPENDIX E ASSESSMENT OF RNERS AS TO THEIR ELIGIBILITYAND SUITABILITY FOR DESIGNATION UNDER THE WILD AND SCENIC RIVERS ACT I. INTRODUCTION The Wild and Scenic Rivers Act, as amended, was enacted by Congress to provide Federal protection for selected free-flowing rivers within the United States. During the initial preparation of the Draft Envl- ronmental Impact Statement (DEIS) and The Proposed Land and Resource Management Plan for the Wenatchee National Forest, a study of certain rivers on the Forest was undertaken to determine their potential eligibility and suitability for inclusion in the Wild and Scenic River System. At that time, the study was confined, with the exception of the Entiat drainage, to those rivers listed on the Nationwide Rivers Inventory, originally published by the Department of Intenor in 1980, and updated in 1982. This inventory was developed to identify rivers which would, by virtue of then exceptional natural, cultural, scenic or recreation resources, qualify for further consideration for inclusion in the National Wild and Scenic River System. The Wenatchee, White and Chiwawa Rivers, and Icicle Creek were identifed in the mventory as meeting these criteria. The mitial Forest planning effort also included the Entiat River and two tributaries, in response to public interest expressed at that time. As a result of both in-Service review and the analysis of comments received from the public during the comment period for the DEIS, the Forest Supervisor assigned an Interdisciplinary (ID) Team the task of malong a reassessment of eligibility for all rivers on the Wenatchee National Forest.

  • Salmon, Steelhead, and Bull Trout Habitat Limiting Factors
    Salmon, Steelhead, and Bull Trout Habitat Limiting Factors For the Wenatchee Subbasin (Water Resource Inventory Area 45) and Portions of WRIA 40 within Chelan County (Squilchuck, Stemilt and Colockum drainages) FINAL REPORT NOVEMBER 2001 Carmen Andonaegui WA State Conservation Commission Headquarters Office: P. O. Box 47721 Olympia, Washington 98504-7721 ACKNOWLEDGMENTS In accordance with RCW 77.85.070 (Salmon Recovery Act, previously Engrossed Senate House Bill 2496), a Technical Advisory Committee (TAC) was organized in March 2000 by the Conservation Commission in consultation with Chelan County, the Yakima Nation (YN), and the Colville Confederated Tribes (CCT), by inviting private, federal, state, tribal and local government personnel with appropriate expertise to participate. The role of the TAC was to identify the limiting factors for anadromous salmonids and bull trout in the Wenatchee subbasin (WRIA 45) and the Squilchuck, Stemilt, and Colockum drainages of WRIA 40 (RCW 77.85.070[3]). The information was then incorporated into this report to support the Chelan County Lead Entity Committee in their effort to compile a habitat restoration/protection projects list, establish priorities for individual projects, and define the sequence for project implementation (RCW 77.85.050[1c]). The TAC membership mailing list was extensive. It included the following persons, although actual participation in the TAC meetings and contribution to the development of the report through draft document reviews were represented by a core group, identified here with an asterisk: Bambrick, Dale National Marine Fisheries Service Bickford, Shane* Douglas County Public Utilities District Bugert, Bob* WA State Governor’s Salmon Recovery Office Cappellini, Malenna* U.S.

Under the Washington State Engrossed Substitute House Bill 2514 Watershed Planning Act, the Wenatchee Watershed Planning Unit (WPU) was formed to guide the development of state watershed planning. Many of the activities relevant to the WPU were highly consistent with NPCC subbasin planning. Co-planners chose to use the WPU and the associated subcommittees (water quality, water quantity, instream flow and habitat) as the primary body for public involvement and development of the subbasin plan. The WPU consists of a wide representation of citizen organizations and government agencies. The subcommittees include representatives from many agencies and stakeholders and are primarily responsible for development of the technical information for WPU consideration. The WPU is currently in its third year of formal recognition by the state of Washington and associated parties. All meetings associated with watershed and subbasin planning were advertised and open to the public. During the early progress of the aquatic assessment, numerous meetings focused upon the development and utilization of the Qualitative Habitat Assessment (QHA) approach, specific to aquatic interests.
